This configuration of the FAST Flame 1 accessory is a combination of 4DX-FAS high-speed autosampler, one precision peristaltic pump and a switching valve. It provides quick sample turnaround with:
- Fast rinse-out
- Short signal stabilization times
- No sample-to-sample memory effect
The FAST Flame 1 accessory rapidly fills a sample loop via vacuum and then switches to inject the sample loop while the autosampler moves to the next sample. This removes the wait time associated with self-aspiration or peristaltic pumping and the long rinse-in and rinse-out times associated with autosampler movement and flushing resulting in sample-to-sample times as short as 15 seconds. Rapid injection and rinse-out result in a throughput of over 560 samples per hour- up to 40% higher than manual analysis for single-element determinations by Flame AA.
FAST Flame 1 provides the ability to:
- Mechanically pump the sample during injection
- Optimize nebulizer and flame conditions
- Eliminate variability due to changes in sample viscosity, dissolved solids and tubing length
- Provide long-term sample flow stability
Linear standard curves and excellent recovery of standard solution concentrations, obtained using FAST Flame 1, demonstrate the system's precision and accuracy, as well as long-term stability.
The 4DX-FAS is an autosampler with dual flowing rinse stations that holds 4 large racks or 6 micro racks. This kit includes one 9-position standards rack for 125ml bottles, two 60-position large sample racks for 15 ml tubes and two 21-position large sample racks for 50 ml tubes.
